A light-controlled meta-surface redirected another beam at femtosecond speeds without relying on slower electronic relaxation. A pulse of light crosses the width of a human hair in roughly 74 femtoseconds (74 quadrillionths of a second). Caltech researchers have now redirected a beam in that same fleeting interval by using a second beam as the control [...]
Researchers at the California Institute of Technology (Caltech) have developed a device capable of redirecting light beams in extremely short time intervals using a system of metasurfaces. This innovation could revolutionize the field of photonic technologies, enabling more efficient communication and information processing. Research and development at Caltech The study was led by Claudio Hail, who conducted the research while a postdoctoral fel…
